Description

Technical Field

[0001] The utility model relates to the field of automated warehousing, and more specifically, to a brake linkage mechanism for a double-column stacker. Background Art

[0002] The double-column stacker is one of the main components of the automated warehouse. Different from the single-column stacker, the frame structure is composed of a rectangular frame consisting of two columns, upper and lower beams, a cargo platform and slide rails. The structural rigidity is better and the mass is greater than that of the single-column stacker.

[0003] Most of the existing double-column stacker loading platforms use elevator-specific safety clamps to achieve rope break protection, but it is impossible to achieve synchronous triggering of the safety clamps on both sides. The reason is that the flexible rope is used for traction, which is not rigid enough, so one is triggered first and the other is triggered later, resulting in the loading platform tilting after the rope breaks, causing the pallet to roll over.

[0004] Therefore, in view of the above problems, a double-column stacker brake linkage mechanism is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a brake linkage mechanism for a double-column stacker to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-column stacker brake linkage mechanism, comprising a cargo platform, both sides of the cargo platform are provided with T-shaped guide rails, and both sides of the cargo platform are fixed with safety clamps, the safety clamps are connected with lifting rods, and one end of the lifting rods is hinged with an adjusting rod, and the bottom of the adjusting rods is hinged with a swing arm, a speed limit rope is provided on one side of the cargo platform, and the speed limit rope is connected with a speed limit rope mounting plate, and the speed limit rope mounting plate is fixedly connected to the lifting rod;

[0007] A lifting device is installed on the cargo platform at one end of the safety clamp, and a brake line is connected to the lifting device. A brake line fixing bracket is fixed on the cargo platform above the lifting rod, and the brake line passes through the brake line fixing bracket and is connected to the top of the lifting rod. Lifting detection devices are installed on both sides of the cargo platform near the lifting rod.

[0008] Preferably, two wedges are symmetrically arranged in the safety clamp, and the wedges are respectively arranged on both sides of the T-shaped guide rail, and the wedges are connected to the lifting rod.

[0009] Preferably, the pulling and hanging device includes a wedge-shaped hanging rod, a compression spring and a pulling and hanging seat, the wedge-shaped hanging rod is hung with a steel wire rope, and the bottom of the wedge-shaped hanging rod forms an elastic reset structure with the pulling and hanging seat through the compression spring.

[0010] Preferably, the suspension seats are all connected to the brake lines, and suspension detection devices are installed on the suspension seats via bolts.

[0011] Preferably, the adjusting rod comprises a hexagonal connecting rod and spherical bearings symmetrically arranged at both ends of the hexagonal connecting rod, and the hexagonal connecting rod is designed to be adjustable in length.

[0012] Preferably, the swing arms are fixed on both sides of the cargo platform by means of expansion sleeves and seat bearings, and a rigid transmission is formed between the swing arms by means of a transmission shaft.

[0013] Preferably, a linear sliding module is installed on the cargo platform below the brake line fixing bracket, and the linear sliding module includes a vertically arranged slide rail and a slider slidably connected to the slide rail, and the lifting rod is connected to the slider of the linear sliding module.

[0014] The technical effects and advantages of the utility model are as follows: compared with the prior art, the brake linkage mechanism of the double-column stacker is provided with a safety clamp, a lifting rod, an adjusting rod and a transmission shaft. The two wedge blocks in the safety clamp are respectively arranged on both sides of the T-shaped guide rail, and the wedge blocks are connected to the lifting rod. The upward movement of the lifting rod can drive the wedge blocks to move upward and clamp the T-shaped guide rail. The lifting rod on either side can drive the adjusting rod to move upward along the linear sliding module, so that the swing arm can rotate upward, and a rigid transmission is formed between the swing arms through the transmission shaft, that is, the rotation of the swing arm on one side can make the swing arm on the other side rotate at the same time through the transmission shaft, and then the lifting rods on both sides are lifted upward at the same time, so that the safety clamps on both sides lock the T-shaped guide rail at the same time. Compared with the traditional method of using flexible rope traction and triggering locking one after the other, the synchronous locking design can avoid problems such as tilting of the cargo platform after the rope of the cargo platform breaks.

[0029] A pulling device 5 is installed on the cargo platform 2 at one end of the safety clamp 4, and a brake line 14 is connected to the pulling device 5. A brake line fixing bracket 6 is fixed on the cargo platform 2 above the lifting rod 8, and the brake line 14 passes through the brake line fixing bracket 6 and is connected to the top of the lifting rod 8. Lifting detection devices 17 are installed on both sides of the cargo platform 2 near the lifting rod 8.

[0030] Among them: the lifting rod 8 moves up to drive the safety clamp 4 to work and lock the T-shaped guide rail 1. After the lifting rod 8 rises, the lifting detection device 17 cannot recognize the signal and the equipment stops running. Example

[0031] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working methods. Figures 1 to 11 As shown, see the following description for details:

[0032] As a preferred embodiment, two wedges are symmetrically arranged in the safety clamp 4, and the wedges are respectively arranged on both sides of the T-shaped guide rail 1, and the wedges are connected to the lifting rod 8; further, the upward movement of the lifting rod 8 can drive the wedges to move upward, clamp the T-shaped guide rail 1, and achieve locking.

[0033] As a preferred embodiment, the lifting device 5 includes a wedge-shaped lifting rod 501, a compression spring 502 and a lifting seat 503. The wedge-shaped lifting rod 501 is hung with a steel wire rope, and the bottom of the wedge-shaped lifting rod 501 forms an elastic reset structure with the lifting seat 503 through the compression spring 502; further, the lifting devices 5 on both sides of the cargo platform 2 are hung with steel wire ropes. After the steel wire rope on one side is loosened for a certain distance, the compression spring 502 inside it is released, and the lifting seat 503 moves downward, driving the brake line 14 to pull the lifting rod 8, so that the lifting rod 8 is lifted upward along the linear sliding module 7, driving the safety clamp 4 on the current side to brake.

[0034] As a preferred embodiment, the suspension seats 503 are connected to the brake lines 14, and the suspension detection devices 3 are installed on the suspension seats 503 by bolts; further, the suspension detection devices 3 can detect the state of the suspension devices 5, and when it is detected that the suspension devices 5 are in the braking state, the equipment stops running.

[0035] As a preferred embodiment, the adjusting rod 9 includes a hexagonal connecting rod 901 and a spherical bearing 902 symmetrically arranged at both ends of the hexagonal connecting rod 901, and the hexagonal connecting rod 901 is designed to be length-adjustable; further, the length-adjustable design enables the adjusting rod 9 to drive the swing arm 13 to rotate upward, and the transmission is smoother.

[0036] As a preferred embodiment, the swing arms 13 are fixed on both sides of the cargo platform 2 by means of expansion sleeves 12 and seat bearings 11, and a rigid transmission is formed between the swing arms 13 through the transmission shaft 10; further, a rigid transmission is formed between the swing arms 13 through the transmission shaft 10, that is, when the swing arm 13 on one side rotates, the transmission shaft 10 can make the swing arm 13 on the other side rotate at the same time, and then the lifting rods 8 on both sides are lifted upward at the same time, thereby realizing the simultaneous locking of the T-shaped guide rail 1 by the safety clamps 4 on both sides, and the synchronous locking of both sides, with a better locking effect.

[0037] As a preferred embodiment, a linear sliding module 7 is installed on the cargo platform 2 below the brake line fixing bracket 6, and the linear sliding module 7 includes a vertically arranged slide rail and a slider slidably connected to the slide rail, and the lifting rod 8 is connected to the slider of the linear sliding module 7; further, the linear sliding module 7 can limit the movement of the lifting rod 8 so that it can only move up and down relative to the linear sliding module 7 but not swing left and right, and the design is more reasonable.

[0038] The working process of the utility model is as follows:

[0039] When in use, the lifting rod 8 moves upward to drive the wedge block upward to clamp the T-shaped guide rail 1. The lifting rod 8 on either side rises along the linear sliding module 7 to drive the adjusting rod 9 to move upward, thereby causing the swing arm 13 to rotate upward. The swing arms 13 form a rigid transmission through the transmission shaft 10, that is, when the swing arm 13 on one side rotates, the transmission shaft 10 can make the swing arm 13 on the other side rotate at the same time, thereby making the lifting rods 8 on both sides lift upward at the same time, thereby achieving the simultaneous locking of the T-shaped guide rail 1 by the safety clamps 4 on both sides.

[0040] State 1: loose rope brake linkage:

[0041] There are steel wire ropes on the lifting devices 5 on both sides of the cargo platform 2. After the steel wire rope on one side is loosened for a certain distance, the compression spring 502 inside it is released, causing the lifting seat 503 to move downward, driving the brake line 14 to pull the lifting rod 8, so that the lifting rod 8 is lifted upward along the linear sliding module 7, driving the safety clamp 4 on the current side to complete the braking.

[0042] State 2: Rope breaking brake linkage:

[0043] When the lifting wire rope of the cargo platform 2 breaks, the cargo platform 2 falls freely, and the speed limit rope 15 pulls the speed limit rope mounting plate 16 in the reverse direction, directly driving the lifting rod 8 to rise along the linear sliding module 7, thereby driving the safety clamp 4 on the side to complete the braking.

[0044] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
